I'm not really using my mac much, so not for me. Interesting though - I've thought it would be neat to have something that's similar though different.

Imagine a keyboard which was itself a mini computer. You could program macros into the keyboard itself, and then have them issued to the computer. Instead of the keyboard being a dumb entry into the computer, it becomes more like of an input client.

From seeing your product I realise - you could do something similar to this with the keyboard driver, and then have all the benefit of a high quality off-the-shelf keyboard.
